Hmmm - if it were just going to doctor's offices, I'd say "Just what the Doctor ordered". I like some of the other suggestions - square meals is cute. Good luck!

go with something simple that states what you do. You have a very targeted market so stay with that in your name. If people already know your name, use it! It gives credibility and stability as you've had your name for a long time. Stay away from anything too "cutsy" that makes people have to guess what it is.

I like the Out of the Box Lunch and Square Lunch that people have mentioned for those reasons.

I also liked the suggestion for Square Meals.
